I need some help explaining how the sensitivity works with different subs. If it has a low number, it doesn't take a lot of power to make the bass. A higher number takes more power. Is this a correct statement? Or is it the opposite?

Opposite. Higher sensitivity means higher SPL with the same power input and in the same enclosure.

And the same measurement technique, and the same motor topology......... posted_image

Sensitivity can be somewhat helpful, but isn't everything.

That's one of the things I love about you, Steven, you keep me honest. I should have said "all else being equal"...

Oh, I was just trying to add to what you said and to further my point that sensitivity shouldn't be the only thing you look at. Your post was just fine to answer his question.

I have learned to throw about everything out the window. last show we were at I dont know if people just cant design a box or what. you will see memphis mojo's and other such larger sub. 300 oz mags. 3 inch surround, 4 inch voice coil 92 and up sensetivity and no one hit over a 145 problems? yes. our eclipses have a 96 oz mag. 2 inch voice coil, 89db sesivity. and we hit a 141 using 200 watts of real power per sub
